Size of Batch using Total Non-Productive Time Solution

STEP 0: Pre-Calculation Summary

Formula Used

Batch Size = Non-Productive Time/Setup Time
N_b = NPT/t_s
This formula uses 3 Variables

Variables Used

Batch Size - Batch Size is the count of similar kinds of products to be manufactured.
Non-Productive Time - (Measured in Second) - Non-Productive Time is the total time wasted in setting up the machine or workpiece for a particular process.
Setup Time - (Measured in Second) - Setup Time of each component is the time required to load/unload the workpiece and position the tool for production for one component.

STEP 1: Convert Input(s) to Base Unit

Non-Productive Time: 20 Minute --> 1200 Second (Check conversion here)
Setup Time: 0.9 Minute --> 54 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

N_b = NPT/t_s --> 1200/54

Evaluating ... ...

N_b = 22.2222222222222

STEP 3: Convert Result to Output's Unit

22.2222222222222 --> No Conversion Required

FINAL ANSWER

22.2222222222222 ≈ 22.22222 <-- Batch Size

< 9 Total Production Time Calculators

Total Production Time given Time for Individual Operation and Batch Size

Go Total Production Time = (Batch Size*Setup Time+Batch Size*Machining Time+Number of Tools Used*Time to Change One Tool)

Total Production Time

Go Total Production Time = (Total Machining Time+Non-Productive Time+Total Tool Changing Time)

Total Production Time given Total Machining and Operating Cost

Go Total Production Time = Total Machining And Operating Cost/Machining and Operating Rate

Machining Time for one Component using Total Machining Time

Go Machining Time = Total Machining Time/Batch Size

Total Machining Time or Total Machine Time

Go Total Machining Time = Batch Size*Machining Time

Size of Batch given Total Machining Time

Go Batch Size = Total Machining Time/Machining Time

Load or Unload or Setup Time given Total Non-Productive Time

Go Setup Time = Non-Productive Time/Batch Size

Size of Batch using Total Non-Productive Time

Go Batch Size = Non-Productive Time/Setup Time

Total Non-Productive Time

Go Non-Productive Time = Batch Size*Setup Time

Size of Batch using Total Non-Productive Time Formula

Batch Size = Non-Productive Time/Setup Time
N_b = NPT/t_s

Managing Non-Productive Time

The reduction of non-productive time is one of the key elements to remain competitive in a fabricating environment. This is usually done by:
1. Control front end processing time
2. Analyze total cycle time
3. Maintain machine cycle time
4. Reduce total order turnaround
